1Blocker Review 2026: What Your iPhone Has Been Missing

1Blocker is one of the best ad blockers for Apple users because it was designed specifically for the platform and works well. It has consistently thwarted YouTube's ads and blocked most of them during repeated in-house testing. I also appreciated how easily I could customize blocking with its toggles for ads, trackers, and other annoyances, like cookies and pop-ups.

Our experience

1Blocker improved my iOS and macOS experience. I was able to seamlessly browse the web, use apps, and click links without worrying about constant tracking. 

With all ad blockers I've tested and reviewed, I visit the Forbes homepage because it's riddled with ads. 1Blocker got to work, blocking 12 requests, including ads, trackers, and other annoyances. This number is pretty good compared to most results, which typically don't exceed 20 ads blocked.

I like that 1Blocker's dashboard includes all the toggles I can enable and descriptions of how they work. I could simply turn on the toggle and let 1Blocker do the rest, or click through each individual toggle for more customization. 

In past testing, I found that certain app features didn’t perform as well when all 1Blocker functions were enabled. I also found that some images failed to load on sites and within emails. 

This was an easy fix, however. 1Blocker allowed me to disable the firewall for a limited time, which enabled me to view these images (which I realized were laden with trackers).

I definitely recommend 1Blocker if you’re looking for an effective ad blocker for macOS or iOS.

Mobile experience

1Blocker is just as easy to integrate into your iPhone app arsenal. Once the app was installed, 1Blocker linked me to Safari settings to enable all its toggles. I enabled the scripts to run. 

I then decided which 1Blocker extensions I wanted to run. The free ad blocker is limited, however.

It has the same list of toggles as on Safari, so all I had to do was decide what kind of content I wish to block and let the app do the work. I could click through the toggle categories and find specific types of content to block, too.

1Blocker can’t block ads in the YouTube app, which is typical for mobile ad blockers, but it can block ads on the YouTube website. I tested this function out and can confirm it works. In the past, 1Blocker received perfect scores on the AdBlock Tester and Can You Block It tests. However, repeated testing has shown the AdBlocker Tester score to drop, and 1Blocker has been consistently unable to block interstitial ads. Even still, it's a strong native ad blocker for iOS. 

1Blocker paid plan

1Blocker has a free version and paid plans for $1.25–$2.99/mo. There are three subscription options but the only difference is the length of your subscription. 

The first tier is monthly and costs a reasonable $2.99/mo. The annual plan is $1.25/mo, which is also affordable. 

Plus, there's a lifetime plan for $39.99 that’s a one-and-done payment. If you plan to use 1Blocker for three or more years, consider the one-time payment plan so you never have to worry about it renewing.

If you want to get the most out of 1Blocker by accessing all the content blocking it has to offer, you’ll need to go with a paid plan. In addition to unlocking all the current features, you’ll also receive weekly updates and early access to new features before free users.

Main features

The features and customization options on 1Blocker’s paid plan are extensive and highly customizable. Features for Safari are broken down into General, Regional, and Custom options.

There’s also a firewall feature that blocks in-app trackers. When you open social media apps, 1Blocker stops them from collecting data on everything else you’re doing on your device, or where you’re going if your location services are active. 

General

The general Safari filters include:

• Block ads on sites
• Block web trackers
• Block annoyances, such as mobile app banners and crypto mining
• Block widgets
• Block comments where they aren’t the primary focus
• Block adult sites

Regional

The regional Safari filters block ads in these specific countries:

• Russia
• Germany
• Spain
• Italy
• France
• China
• Japan
• Holland (Dutch)
• Poland

Custom

Custom rules allow you to create your own options on webpages by using the app’s templates. These rules include:

• Allow List: Turn off blocking for your favorite sites
• Block Sites: Configure rules to block any site or page
• Block Cookies: Ignore cookies when sending requests to sites
• Hide Elements: Visual editor for hiding buttons, sidebars, or other elements
• Force HTTPS: Allows you to make websites HTTPS-only

Firewall

The firewall feature is useful for blocking in-app trackers. Trackers can do anything from collecting data on the other sites you’re using (and what you’re looking at on those sites) to allowing apps to continue tracking your geolocation if your location services are turned on. 

If you want to avoid constant tracking, 1Blocker’s firewall can help. It even integrates with Siri to let you toggle it on and off via voice commands.

1Blocker's test results

We use AdBlock Tester and Can You Block It to test how well an ad blocker works. 

AdBlock Tester uses various analytics and advertising services to see how effective an ad blocker is when installed. Can You Block It checks your ad blocker's effectiveness against interstitial ads, ad blocker detection warnings, and banner ads.

First, 1Blocker received an okay score from AdBlock Tester. It has consistently earned perfect scores prior to this test, so this result could be a fluke. 

Then, 1Blocker got a near-perfect Can You Block It score. It blocked the banner ads and ad blocker warning completely; it just failed to skip over the interstitial ad.

1Blocker scores

	AdBlock Tester	Can You Block It
1Blocker score	78/100	2.5/3

YouTube ad test

Yes, 1Blocker does a great job of blocking YouTube ads without lag time. We started a YouTube video on Google Chrome with no ad blocker enabled. We were bombarded with the usual preroll ads and banner ads.

Then, we swapped to Safari with 1Blocker enabled. Our YouTube stream was seamless with no interruptions.

1Blocker also lets you toggle off ad blocking so you can continue supporting your favorite creators through ad revenue. If you’re using it on a Mac, you can toggle off from the browser extension. If you’re using 1Blocker on an iOS device, you can turn off the " Block Ads " toggle while on YouTube. 

Bypassing paywalls test

We imagine most readers have felt annoyed when opening an article on a site behind a paywall. That's why we test all our ad blockers against paywalls to see which ones can bring them down. 

We didn't expect 1Blocker to bypass paywalls, since most ad blockers we've tested fail this test. It failed against The Wall Street Journal and Bloomberg, but unblocked The Atlantic's paywall. 

Although it didn’t unblock all paywalls we tested, its partial success was promising.

What browsers and software is it compatible with?

1Blocker is built exclusively for macOS, iOS, and Safari. If you’re hoping to install it on other browsers such as Chrome, Edge, or Firefox, or on a Windows, Linux, or Android device, you won’t be able to do that.

Because 1Blocker is built for Apple devices, it integrates seamlessly with each operating system and syncs across your devices. We’ve been using 1Blocker on our Mac and iPhone, and the permissions and whitelists have been transferred. We’re also able to share it with our family members through Apple’s Family Sharing for no additional cost.

How to use 1Blocker

Once you've downloaded 1Blocker on your Apple devices, you'll need to enable content blocking. The settings vary by device, so we'll break down the 1Blocker setup below. 

How to enable content blocking in Safari on iOS:

1. Open your iOS settings.
2. Go to Safari > Extensions.
3. Enable your preferred 1Blocker settings.
   

   

How to enable content blocking in Safari on macOS:

1. Open Safari on your Mac.
2. Go to Safari > Settings > Extensions.
3. Check off all 1Blocker boxes.
   

   

4. Open the 1Blocker app and turn on your preferred content-blocking categories. 

Top alternatives

1Blocker is a great service for Apple users, but it's not compatible with Windows or Android. If your household uses more than just Apple products, you won't be able to block ads on all devices.

The following are some of our favorite 1Blocker alternatives based on their test scores, pricing, compatibility, and more.

Bottom line: Is 1Blocker good?

Yes, 1Blocker is a solid ad blocker. In fact, we've found it to be the best ad blocker for Apple users. Although other ad blockers do work on Apple devices, 1Blocker was built specifically for these operating systems and integrates beautifully. It provides features to prevent tracking and enable a clean browsing experience.  

There are some slight issues with 1Blocker, such as the inability to easily toggle it on and off in Safari on iOS devices, that keep it from being perfect.  

However, the protection, parental controls, and customization options make up for that issue in our opinion. If you’re looking for a way to enhance your experience on your iOS, macOS, and Safari devices, 1Blocker may be the perfect solution.

1Blocker is one of the best apps for Mac, Safari, and iOS devices, but you can also see how our 1Blocker alternatives compare if you need coverage across operating systems: 

• 1Blocker vs. Total Adblock
• 1Blocker vs. AdGuard
• 1Blocker vs. Wipr
• 1Blocker vs. uBlock Origin
